Earlier today i was experiencing freezes in safari on an ipad 2 running ios 6.1. If the freezes return i may have to upgrade to a newer version of ios. After hearing that ios 9 was all about bugfixes and speed improvements, i decided to wait for ios 9 and skip 8.4. Judging from the posts on various webforums that may not have been the smartest decision since many (some?) people are experiencing lag . My questions are: - How is ios 9 doing on your device? Is the general opinion that it's a step back in terms of speed? - Should i install 8.4 while i still can? How long can i still install 8.4 on my ipad 2? Is it ease to install a previous version of ios? - Should i perhaps wait for ios 9.1 instead?
